TECHNICAL FIELD
[0001] The present application relates to the technical field of desalination water mixed bed regeneration device, and particularly relates to a desalination water mixed bed regeneration device. BACKGROUND
[0002] As the core equipment of industrial water treatment system, the regeneration effect of the cation and anion exchange resin in the desalination water mixed bed directly determines the water quality and operation cost. In the prior art, the mixed bed regeneration cycle is usually set to 7 days, and a large amount of water resources and chemical agents are consumed each time. Before the regeneration operation, the resin layer height and distribution state need to be strictly detected, and if the resin layer has collapse, channeling or uneven layering phenomenon, the regeneration liquid will be distributed unevenly, which significantly reduces the regeneration efficiency and aggravates the resource waste.
[0003] At present, the mechanical resin layer detection method is generally used in the industry: the operator needs to vertically insert an elongated measuring rod with scales into the resin layer through the access hole at the top of the mixed bed, and then read the height of the resin surface according to the scales on the rod. However, this manual rod insertion method needs to strictly control the angle and force of insertion, because the cross-sectional area of the measuring rod is small, and in the process of penetrating the resin layer, the resin particles are easily displaced due to local stress concentration, thereby damaging the integrity of the original layering structure.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0022] This application provides a demineralized water mixed bed regeneration device, such as... Figures 1 to 4 As shown, the desalinated water mixed bed regeneration device includes a mixed bed device 1, a limiting rod 3, a displacement plate 4, a measuring rod 5, a displacement rod 7, a connecting rod 8, a contact plate 9, and an automatic locking assembly. An exhaust pipe 2 is provided on the top surface of the mixed bed device 1 for discharging gas during the regeneration process. The limiting rod 3 is fixedly connected to the top surface of the mixed bed device 1, and the displacement plate 4 is slidably connected to the outer wall of the limiting rod 3, allowing the displacement plate 4 to move up and down along the limiting rod 3. One end of the measuring rod 5 is connected to the bottom of the displacement plate 4, and the other end passes through the top surface of the mixed bed device 1 and extends into the interior of the mixed bed device 1 to detect the height of the resin layer. Specifically, the other end of the measuring rod 5 passes through the sealing interface on the top surface of the mixed bed device 1 and extends into the interior of the mixed bed device 1.
[0023] The measuring rod 5 has an internal cavity 6, and a displacement rod 7 is disposed within the cavity 6. A connecting rod 8 is fixedly connected to the lower end of the displacement rod 7. The end of the connecting rod 8 opposite to the displacement rod 7 passes through the bottom of the measuring rod 5 and is fixedly connected to the contact plate 9. The outer wall of the measuring rod 5 has a through groove 10 extending into the interior of the measuring rod 5. A sliding block 11 is slidably connected inside the through groove 10. The upper surface of the sliding block 11 is set as an inclined surface. The displacement rod 7 is equipped with an automatic locking component, which is used to automatically lock the measuring rod 5 after the contact plate 9 contacts the resin layer to prevent the measuring rod 5 from continuing to move downward and causing disturbance to the resin layer.
[0024] Specifically, the application increases the contact area with the resin layer through the wide surface contact design of the contact disc 9, effectively reduces the local pressure, thereby avoiding the displacement of resin particles or the collapse of the layer structure. At the same time, through the linkage mechanism of the automatic locking assembly, the automatic locking of the measuring rod 5 can be completed immediately after the contact disc 9 contacts the resin layer, preventing the measuring rod 5 from penetrating too deeply into the resin layer, and further protecting the structural integrity of the resin layer.
[0025] In the embodiment of the application, the automatic locking assembly includes a tapered block 12. The tapered block 12 is sleeved on the outer surface of the displacement rod 7 and can move up and down with the displacement rod 7. The sliding block 11 is in sliding contact with the tapered outer surface of the tapered block 12 on one side surface inside the cavity 6, and the inclination angle of the inclined surface of the sliding block 11 matches the taper angle of the tapered block 12. When the contact disc 9 is pressed to move upward, the displacement rod 7 drives the tapered block 12 to move upward, and the tapered outer surface of the tapered block 12 cooperates to drive the sliding block 11 to expand radially outward, so that the sliding block 11 is frictionally locked with the inner wall of the measuring rod 5.
[0026] It should be noted that the inclined surface cooperation mechanism of the tapered block 12 and the sliding block 11 of the application realizes positive feedback of contact force-friction force.
[0027] In the embodiment of the application, the bottom of the displacement plate 4 is fixedly connected with a push rod 13, and the outer side wall of the mixed bed device 1 is fixedly connected with a limiting block 14. The side surface of the limiting block 14 is provided with a limiting groove 15 extending in the vertical direction, and the lower end of the push rod 13 is slidingly inserted into the limiting groove 15 for limiting the horizontal deflection of the displacement plate 4.
[0028] In the embodiment of the application, the desalted water mixed bed regeneration device further includes a mounting plate 16 and a threaded rod 17. The mounting plate 16 is fixedly connected to the inner wall of the limiting groove 15. One end of the threaded rod 17 is connected to the push rod 13, and the other end of the threaded rod 17 passes through the threaded hole of the mounting plate 16 and is threadedly connected.
[0029] In the embodiment of the application, the side of the threaded rod 17 away from the push rod 13 is fixedly connected with a knob 18.
[0030] In the embodiment of the application, the side surface of the limiting block 14 is provided with a scale groove 19 along the length direction of the limiting groove 15, and the calibration scale of the scale groove 19 corresponds to the resin layer height detection range.
[0031] It should be noted that when the measuring rod 5 penetrates, the operator can conveniently use the push rod 13 at the same horizontal height as the measuring rod 5 to directly read the scale value, thereby greatly simplifying the observation process of the value and improving the convenience and accuracy of the measurement. Such a design not only ensures the intuitiveness of the measurement, but also effectively improves the work efficiency.
[0032] In the embodiment of the present application, the outer wall of the knob 18 is provided with anti-skid lines, which can increase the friction between the outer wall of the knob 18 and the fingers of the operator.
[0033] The working process of the desalted water mixed bed regeneration device of the present application is as follows:
[0034] When measuring the height of the resin layer inside the mixed bed device 1, first rotate the knob 18. The rotation of the knob 18 will synchronously drive the threaded rod 17 to move in the vertical direction. The movement of the threaded rod 17 in turn drives the push rod 13 connected thereto to move. The push rod 13 will synchronously drive the displacement plate 4 to slide up and down along the limiting rod 3. The sliding of the displacement plate 4 in turn drives the movement of the measuring rod 5, and the lower end of the measuring rod 5 indirectly drives the movement of the contact disc 9.
[0035] When the contact disc 9 contacts the resin layer, due to its wide surface design, the contact area is increased, thereby reducing the local pressure on the resin layer. After the contact disc 9 is pressed and stops moving, the displacement rod 7 and the connecting rod 8 connected to the contact disc 9 also stop moving synchronously. At this time, if the measuring rod 5 continues to move downward, it will cause relative movement between the displacement rod 7 and the sliding block 11.
[0036] The sliding block 11 is driven by the measuring rod 5 and cooperates with the design of the tapered block 12 to be pushed out of the inside of the through slot 10. Since the lower surface of the sliding block 11 is designed as a flat surface, the lower surface of the sliding block 11 contacts the top surface of the mixed bed device 1, forming a mechanical limit and completely preventing the measuring rod 5 from continuing to move downward. At this time, the operator can read the height of the push rod 13 by means of the scale groove 19 of the limiting block 14, thereby determining the height of the resin layer.
[0037] After the measurement is completed, the measuring rod 5 needs to be raised for resetting. Since the upper surface of the sliding block 11 is designed as an inclined surface and under the action of gravity, the displacement rod 7 and the tapered block 12 will reset. At this time, the sliding block 11 located inside the mixed bed device 1 lacks the block of the tapered block 12, and cooperates with the design of the inclined surface to be smoothly retracted into the inside of the through slot 10. Subsequently, the operator only needs to manually push the sliding block 11 located outside the mixed bed device 1 into the inside of the through slot 10, thereby completing the resetting of the entire measurement process.
[0038] Each embodiment in the present specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.
